Instructions for the REFINER experimental data

Please ensure that both REFINER and the mCRL2 toolset are correctly installed.

The experimental data archive contains a number of folders, each containing a model, at least one rule system to refine the model,
and some properties to check on the model and the rule system.
There is a file called README.txt present in each folder, offering information on the specific file names.

This information can be used to transform the network, and check for property preservation of the rule system(s).
To give an impression of the possibilities when running from the command-line, we list the standard operations with REFINER using the IDs of the README example given above.

Check that a rule system is semantics preserving. If not, produce a counter-example:refiner -c RSYSTEM
Check that a property is preserved by a rule system for network in general. If not, produce a counter-example:refiner -p PROP1 -c RSYSTEM
Check that a property is preserved by a rule system when applied on a given network. If not, produce a counter-example:refiner -p PROP1 -c RSYSTEM -n NETWORK
To use multiple cores to perform checking in parallel, use the -t option, with nc the number of cores:refiner -p PROP1 -c RSYSTEM -t nc -n NETWORK
If the property is either a safety or a fairness property, the following can also be invoked:refiner -p PROP1 -c RSYSTEM -f -t nc -n NETWORK
Finally, if a liveness property must be checked, divergency information about the network can be incorporated in the check:refiner -p PROP1 -c RSYSTEM -d -t nc -n NETWORK

Transform the network according to a rule system:refiner -r RSYSTEM -n NETWORK
A possible option is to propagate divergency information along transforming, to avoid having to compute this for transformed models:refiner -r RSYSTEM -d -n NETWORK

When running REFINER with the GUI, by default, 8 threads are run when verification is performed. Other numbers can be set at the command line, when launching refiner-gui:refiner-gui -t nc
Besides creating and editing rule systems, the GUI offers the same options as the ones listed above for the command-line version.
